As shown in Figure 1 to Figure 4.

An air duct type indoor unit with humidification function includes a casing 1, a fan 2, a heat exchanger 3 and a humidification structure.

The casing 1 includes an air inlet and an air outlet 22. The air outlet 22 is located on one side of the casing 1, and the air inlet may be provided on the bottom plate 8 of the casing 1. The humidification structure, the heat exchanger 3 and the fan 2 are sequentially installed from the air outlet 22 to the inside of the casing 1, and the air outlet of the fan 2 faces the heat exchanger 3, so that the air driven by the fan 2 depends on The sequence flows through the heat exchanger 3 and the humidification structure to adjust the temperature and humidity of the air. A water receiving box 4 is provided under the heat exchanger 3 to receive the condensed water generated by the heat exchanger 3. Preferably, there are two fans 2 arranged in parallel to provide sufficient power. There are two heat exchangers 3, which are connected to each other in an upright V shape, with their tips facing the air outlet, which can improve the heat exchange effect.

The humidification structure includes a humidification sheet assembly and a water pan assembly.

The water tray assembly includes an upper water tray 19 and a lower water tray 9. The upper water tray 19 is box-shaped with an open upper end. The drain pan 9 is in the shape of a rectangular box with an open upper end and one side, similar to a "dustpan" shape. The height of the upper water tray 19 is smaller than the depth of the lower water tray 9 and is connected to the lower water tray 9 through a bracket I20. Preferably, a flash is provided on the upper edge of the upper water tray 19, which can overlap the upper edge of the lower water tray 9 and separate the bottom of the upper water tray 19 from the bottom of the lower water tray. It is convenient for the water accumulated in the drain pan 9 to flow. The upper water tray 19 is provided with a water inlet pipe 12 for connecting an external water source, such as tap water, to fill the upper water tray 19 with water. The water inlet pipe 12 can be installed on the water inlet sealing plate 13. The water inlet sealing plate 13 is in the shape of a short plate, which can be installed at one end of the drain pan 19 and its lower end is fixedly connected to the bottom plate 8 of the casing 1. The other end of the drain pan 9 can be fixed to the bottom plate 8 of the casing 1 through a bracket II7 so that the bottom of the drain pan 9 is higher than the water receiving box 4. The corners of the upper end of the upper water tray 19 are respectively provided with overflow holes 23 penetrating inside and outside, so that excess water can flow into the lower water tray 9 from the overflow holes 23 to avoid overflow. The lower edge of the open side of the drain pan 9 is provided with a deflector 6. The deflector 6 inclines below the drain pan 9 and overlaps with the water receiving box 4 so that the accumulated water in the drain pan 9 can flow into the receiving water along the deflector 6 In box 4, avoid overflow and affect normal use.

The humidifying sheet assembly includes a plurality of humidifying sheets 10. The humidifying sheet 10 can be made of composite fibers and has strong water absorption. Each humidifying sheet 10 has the same shape, and is a T-shaped flake, with a downward protrusion 17 provided on the right end. The end of the protrusion 17 is pointed, which facilitates the excess water on the humidifying sheet 10 to flow out from the end. A dividing groove 16 is provided in the middle of the humidifying sheet 10. The dividing groove 16 is an obtuse angle V-shaped, vertically arranged, and the opening faces the right side of the humidifying sheet 10, so that excess water on the humidifying sheet 10 can flow from the left side of the dividing groove 16 to its right side, and then along the The protrusion 17 flows out. Preferably, the angle of the dividing groove 16 may be 120-130°. The inner recess on the left side of the humidifying sheet 10 is provided with a connecting groove 18. The connecting groove 18 has a flat rectangular shape and can be clamped on the elongated connecting rod 11 so that the humidifying chips 10 are arranged vertically. The two ends of the connecting rod 11 are fixed to the two ends of the upper water tray 19, so that the lower part of the humidifying sheet 10 is placed in the upper water tray 19, and the protrusion 17 is located on the upper water tray 19 19 and point to the lower drain pan 9, so that the humidifying sheet 10 can absorb the moisture in the upper drain pan 19 for humidification. At the same time, excess unevaporated water can flow out from the protrusion 17 into the lower drain pan 9, and at the same time, the impurities on the humidifying sheet 10 can be taken away with the water flow to ensure that the water in the upper drain pan 19 is clean. .

Further, the left side, right side, and lower end of the humidifying sheet 10 are respectively provided with fixing grooves 15 and are respectively clamped on the three fixing rods 14. The fixing rod 14 is in a zigzag shape, which can make each humidifying chip 10 fit into the tooth groove, ensuring that the humidifying chips are parallel to each other and are evenly spaced. The fixed groove 15 and the fixed rod 14 have the same cross-sectional shape and are both flat and rectangular, so that the two can be easily connected.

The invention also includes a wind deflector 5. The cross section of the wind deflector 5 is an obtuse angle V-shaped, and its length is equivalent to the open side of the drain pan 9, so that the upper side wall of the wind deflector 5 is installed on the open side of the drain pan 9. The lower side wall is suspended in the front and above the deflector 6, which can ensure that the outlet wind blows to the humidification sheet assembly along the deflector 5, and prevents the air from the air outlet from directly blowing on the deflector 6 , Affecting the normal flow of water. The angle of the wind deflector 5 can be 135-150°.

The present invention also includes a float switch assembly 21. The float switch assembly 21 is arranged in the upper water tray 19 and is connected to the water inlet pipe 12 to automatically control the water inlet. The float switch assembly 21 and the humidification sheet assembly are respectively installed on both sides of the upper water tray 19, therefore, the upper side wall of the wind deflector 5 is stepped, and its lower end corresponds to the humidification The upper end of the sheet assembly corresponds to the float switch assembly 21, so that it can not only ensure that the wind blows to the humidification sheet assembly, but also enable the float switch assembly to be shielded by the wind deflector to avoid wind Influence. Preferably, the float switch assembly 21 can be Fuji Seiko C-0200105.

The bracket I20 and the bracket II7 are both sheet metal parts, which can be designed into suitable shapes and sizes according to requirements.
